Forging Screw Press

A screw press is a forging machine that uses screws and nuts as drive mechanisms and transforms negative and positive rotary movement of fly wheel into upward and downward reciprocating movement of sliding block. At work, electric motor makes fly wheel rotate in an accelerating way and store energy, and push the sliding block to move downward through screw and nut. When the sliding block touches the workpiece, the fly wheel is forced to reduce speed till stop completely, and rotary kinetic energy that is stored is transformed into impact energy and strike the workpiece via the sliding block and make it be distorted. After strike is over, electric motor makes the fly wheel rotate in a reverse way and bring the sliding block to ascend and return to the original position. The specification of a screw press is shown with nominal work force.
